ABSTRACT:
CMOS optical receiver and optical transmitters are described. The optical receiver is formed from a CMOS CCD which is modified to immediately output all information indicative of incoming light, i.e., with no transfer gate. The optical transmitter is formed of a modulation window device. Both the optical transmitter and optical receiver are located on-chip with a microprocessor and form the I/O for the microprocessor. Since the modified I/O is serial, a serial to parallel converter, and parallel to serial converter are provided.
